Abstract
本发明公开了一种用于桥梁体外预应力齿块的免拆UHPC模板及其制作方法，属于桥梁工程加固技术领域。该模板包括一个整体预制的开口箱型结构，由立面模板、两块侧面模板和底板模板在工厂一次成型。所述开口箱型结构内侧表面均匀布设有预埋的弯角钢筋桁架，弯角钢筋桁架的底部锚固筋嵌入UHPC基体；侧面模板上预留锚固孔，用于穿设化学锚栓与箱梁主体固定；立面模板上开设有注浆孔和出浆孔，用于浇筑齿块灌浆料；其制作方法包括模具制作、钢筋桁架定位、UHPC浇筑养护、开孔预埋等步骤。本发明通过整体式模板结构消除了现场拼缝，UHPC模板与齿块结构共同受力并提供较强约束力，解决混凝土齿块结构易开裂的问题，具有整体性强、施工便捷、耐久性优异的特点。
